BATF financial fun

"Agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives used a secret, off-the-books bank account to rent a $21,000 suite at a Nascar race, take a trip to Las Vegas and donate money to the school of one of the agent's children, according to records and interviews."

They were investigate cigarette smuggling, and when an informant operating as a smuggler began making big profits, they used them to set up their own private account.
